Im just curious because I can’t really find it anywhere. Btw I’m not even in college yet so i don’t have any “Stats.”
Since you’re not even in college, I’d feel a little funny describing things you have no knowledge of or experience with. Why don’t you go to college and get some experience in the sciences before you start calculating your chances?
So, let me give you this broad explanation. The whole world is competitive. In any program, anywhere, there are students (participants) who do better and some who do worse. The most desirable opportunities nearly always go those who distinguish themselves. Many people can get a doctorate in Immunology, but not all of them can write grants that attract support.
